MCP48CMD02T-E/MF

Overview

The MCP48CMD02T-E/MF is a dual-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) memory and an SPI serial interface. It operates on a single supply voltage ranging from 1.8V to 5.5V. The device supports reference sources including VDD, external VREF, or an internal band gap. Key electrical specifications include a typical settling time of 4 µs, a gain error of ±0.1% FSR, and an Integral Nonlinearity (INL) of ±0.1 LSB. It provides selectable unity or 2x output gain and includes power-down modes for low-power applications.

Feature Summary

• Integrates nonvolatile MTP memory for retaining configuration and output values across power cycles.
• Supports multiple voltage reference sources including device supply, external pin, and internal band gap.
• Features a high-speed SPI interface with write speeds up to 50 MHz.
• Includes configurable power-down modes to disconnect the output buffer or select pull-down resistors.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring persistent configuration data
• Low-power portable instrumentation
• PC peripherals and data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure that the required operating temperature range and voltage levels match the system design constraints before finalizing procurement.

Selection Notes

Select this component when dual-channel conversion with nonvolatile storage is required. Compare INL and settling time specifications against application requirements. Verify compatibility with the host microcontroller's SPI mode and voltage levels. Consider the MTP programming voltage requirements if field reconfiguration is necessary.

Part Context

This part belongs to the MCP48CXDX1/2 family, which encompasses single and dual channel DACs with resolutions of 8, 10, and 12 bits. The 'CMD' designation indicates the inclusion of nonvolatile MTP memory, distinguishing it from volatile counterparts like the CVD series within the same product line.
